What a "naka" girl needs… is a dekachin (big dick). After the debut shoot she was made to abstain from masturbation for one month, leaving her pussy full of frustrated desire — it engulfs the big dick and she cums so hard her mind goes blank! Her first portio (cervical) experience: wanting it, holding back, and when the big dick is driven into the spot inside her that feels the most, she keeps cumming — she looked genuinely blissful.
